Physiological responses and storage quality of fresh-cut red and white dragon fruit (Hylocereus spp.) treated with 1-methylcyclopropene (1-MCP)

The effects of 1-MCP post-cutting application on the storage quality of fresh-cut red and white dragon fruit were determined using headspace gases (ethylene and CO‚‚) concentration antioxidant activity visual evaluation (water soaking incidence and visual quality rating) and microbiological (yeast and mold count aerobic plate count and total coliform count) quality. Mature red and white dragon fruit were sanitized with ClO‚‚ prior to fresh-cut processing. Gaseous 1-MCP was injected to fresh-cut fruits packed in polyethylene terephthalate (PET) trays with polyvinyl chloride (PVC) stretch film overwrap. These packs were stored at 5-10C and assessed in terms of the storage quality parameters mentioned above. Treatment with 1-MCP positively affected headspace CO‚‚ and ethylene in both species. Fresh-cut white dragon fruit showed better response to 1-MCP as compared to the fresh-cut red dragon fruit in terms of headspace CO‚‚ concentrations. No water soaking incidence was recorded all throughout storage for the 1-MCP treated fresh-cut red dragon fruit while for the fresh-cut white dragon fruit water soaking was observed on the 12th day of storage. For both species 1-MCP delayed visual quality deterioration and increased antioxidant activity. Lower yeast and molds count aerobic plate count and coliform count were observed in both species with 1-MCP treatment. Post-cutting treatment with 5ppm 1-MCP may positively affect storage quality of fresh-cut red and white dragon fruit.

Abstract

The effects of 1-MCP post-cutting application on the storage quality of fresh-cut red and white dragon fruit were determined using headspace gases (ethylene and CO‚‚) concentration antioxidant activity visual evaluation (water soaking incidence and visual quality rating) and microbiological (yeast and mold count aerobic plate count and total coliform count) quality. Mature red and white dragon fruit were sanitized with ClO‚‚ prior to fresh-cut processing. Gaseous 1-MCP was injected to fresh-cut fruits packed in polyethylene terephthalate (PET) trays with polyvinyl chloride (PVC) stretch film overwrap. These packs were stored at 5-10C and assessed in terms of the storage quality parameters mentioned above. Treatment with 1-MCP positively affected headspace CO‚‚ and ethylene in both species. Fresh-cut white dragon fruit showed better response to 1-MCP as compared to the fresh-cut red dragon fruit in terms of headspace CO‚‚ concentrations. No water soaking incidence was recorded all throughout storage for the 1-MCP treated fresh-cut red dragon fruit while for the fresh-cut white dragon fruit water soaking was observed on the 12th day of storage. For both species 1-MCP delayed visual quality deterioration and increased antioxidant activity. Lower yeast and molds count aerobic plate count and coliform count were observed in both species with 1-MCP treatment. Post-cutting treatment with 5ppm 1-MCP may positively affect storage quality of fresh-cut red and white dragon fruit.
